Two 3D objects colliding on a graph and displaying a conditional

I have two objects displayed on a 3D graph that are moving independent of each other and I am attempting to display a congratulations statement when the two objects collide or are equal to each other. However When I write my code it either always displays the congratulations statement or the statement isnt displayed at all. This is the code I have with the if statement for the congratulations message.
